Parasitic DNA stops “jumping” when protein takes charge

Biology researchers Vera Gorbunova and Andrei Seluanov report that the “jumping genes” in mice become active as the mice age when a multi-function protein stops keeping them in check in order to take on another role. A protein called Sirt6 is needed to keep the jumping genes—technically known as retrotransposons—inactive.

Less effective DNA repair process takes over as mice age, biologists find

Biologists Vera Gorbunova and Andei Seluanov have discovered one reason for the the increase in DNA damage as we age: the primary repair process begins to fail and is replaced by one that is less accurate.

Biologist Vera Gorbunova to lead 5-year project on longevity

A $9.5 million grant from the National Institute on Aging will support research into the factors responsible for longevity in various species of long-lived rodents, with the goal of developing treatments to improve the aging process in people.
